Hi Eddy,
unfortunately I can not unsolder the board, but the photos I sent you do see it in all angles.
The only resistors under the board are: R5 (473 ohms), R6 (103), R7 (103), R16 (102), R17 (102).
It could be r5?

Hi Eddy

Too bad, maybe I can take some pictures of the users from the other forum.
let's see

R5 can not be
If a bridge resistor is present, the imprinted 121 or 1200

But I can think of another
measure times with a multimeter between pin 6 and pin 14 the Ohm value

So you can test whether a bridge resistor is present.

Greetings Eddy

Hi,
I measured between pin 6 and pin 14 , and indeed the value is 120 ohms. so there is resistor . now we have to find the bastard resistor :x

Hi Eddy


Comparisons times the interface in the image with your
in this I marked the bridge resistor.

What imprint has the resistance in your
ELM Interface ??

Greetings Eddy

Edit:

Look on page 144 there is the same board as in your interface

Hello Eddy,

unfortunately there is not that resistor in my interface :cry:

Hi,
I have found that there are resistors under the tab at the bottom ( as I indicated in the figure) , where they attack the 16-pin ! how can I get them ? come off the 16 pin from the plastic ?

I solved it! The resistor was under, and not to unsolder everything I removed the plastic under the pin to access it and I removed the resistor. Now everything works perfectly! Eddy Thanks for the advice.

Hello Alfaeddy

Can you help me with this interface, please? Which resistor should I remove? Thank you.

hello

Remove the white (8 times) plug housing
And make a picture of it

Which vehicle ???
